Description:
Civil buildings in urban areas are one of the main sources of CO 2 emissions. Many factors in civil buildings cause CO 2 emissions to increase in China's urban areas. Factors that have influenced CO 2 emissions from civil buildings in Chinese cities between 1997 and 2007 are studied using the Logarithmic Mean Divisia Index method. The following factors influence the increase of CO 2 emissions: urban population, per capita floor space, building structure, building energy intensity and carbon emission coefficients. The results show that, between 1997 and 2007, increase in CO 2 emissions by civil buildings in China's urban areas was largely driven by the increasing urban population and per capita floor space, which have contributed 56 and 87%, respectively, and present a trend of significant increase. The structural proportion change of areas of residential buildings and public buildings caused less of an impact of CO 2 emissions. The reduction in the intensity of energy consumption of buildings is the major factor that could deter the increase in the rate of CO 2 emissions, contributing –45%. However, this deterrence is slowing down. While maintaining the speed of urbanization of China, the key measures to suppress the increase in civil building CO 2 emissions in urban areas are to reduce the intensity of building energy consumption and to control the per capita floor space.
